Even our extensive beta phase didn't reveal a few issues with Teleporter. They will be fixed in this PR. Changes:

• Add export & import for missing tables: group, client + the group linking tables.
• Rename Teleporter Ex-/Import to Backup and Restore to highlight that they are meant for being done on one and the same device rather than for transporting stuff between different installations (even when this is and will stay possible).
• Add pihole-FTL.conf ans custom.list (Local DNS Records) to Teleporter Backup
• Add import for Local DNS Records
• Improve arrangement of check boxes in the Teleporter Import box
• Log number of imported group assignments

We'll need to note in the Release Notes that "Teleporter" is now just Backup/Restore.

I see a small glitch: a break is missing in front of the checkbox for "Local DNS Records"

Edit:
And it is still called Blocklist (v5.0 terminology is Adlist)

Can the option of long term data be there and not be enabled as default?

Maybe a line like this:

empty box Long term data (357Mb)

I would appreciate the possibility of this not only as an exporting/importing tool but also as a general backup tool...

I tried adding it to the Teleporter archive and PHP crashed with out-of-memory. I tried again with slimed down copies (truncated database to the last 6 months, then 3 months, then 2, then 1 and ran VACUUM every time) and only the last iteration worked.

I don't think that's an option, not even a by default disabled one, as it will fail for almost everyone trying this (I have PHP configured to take up to 512 MB of memory).
